Abstract

Abstract In this article, a new partially immersed slow strain rate (SSR) and corrosion-fatigue (CF) test methods are described and discussed. Partial immersion of a specimen in 3.5 % NaCl solution creates an interface between the solution and air. We call this a “chemical notch” stress concentration factor. The outcome of this demonstrates that the SSR test condition on a smooth specimen will fail at the interface if the machined notch stress concentration factor is less than the “chemical notch” stress concentration factor. This “chemical notch” concept can be applied to correlate corrosion-fatigue S–N data for a specific material/environment system.
